# Set DNS settings

## Change the default DNS server

|
On Arch and most modern Linux distributions domain name resolution is handled
|
|
|
|
|
via the `systemd-resolved` #systemd configuration.
|
|
|
|
|
|
|
|
|
|
Within the system systemd files this will be handled in
|

|
|
|
`/etc/systemd/network/wired.network` or `/etc/systemd/network/wlan.network`
|
|
|
|
|
files etc.

In the file below I have turned of DHCP routing and specified the address of my
|

|
|
|
Pi-Hole device to handle domain name resolution:

This stops it using the default DNS server of my router and runs the resolutions
|
|
|
|
|
against Pi-Hole.
